Simple program for updating & upgrading your linux system via command line.

1. Progress bars: Show progress or notifications for long-running tasks.
2. User prompts: More detailed prompts with validation to ensure user input is handled properly.
3. Additional actions: Optionally upgrade distribution(dist-upgrade) and check the system for broken packages(dpkg --configure).
4. Logging: Save logs of the update and upgrade process for later reference.
5. System info: Display system information like the current kernel version and system uptime.
6. Colorized output: Use color to improve readability and make it visually engaging.

1. Color-coded output: The script uses green, yellow, and red colors to indicate success, info, and error messages respectively.
2. System information: Displays kernel version and uptime before starting the upgrade.
3. Progress indicators: Inform the user of the various stages (e.g., updating, upgrading, autoremove).
4. Logging: Logs all the terminal output into /home/root/system_update_upgrade.log for later review.
5. Dist-upgrade option: Adds an optional distribution upgrade for more comprehensive package management.
6. Broken packages check: Ensures that any broken packages are handled.

This program uses sudo, make sure you have admin permissions. The script performs tasks based on user input, and gives clear options at each stage. If any errors occur, the script will notify the user and exit, preventing further issues.

The script works with the APT package manager, which is used by Debian-based distributions like Ubuntu, Mint, and others.

1. apt update updates the package list from repositories.
2. apt upgrade installs newer versions of existing packages.
3. apt dist-upgrade is a more comprehensive upgrade that also installs and removes packages if needed (used for upgrading between major versions).
4. apt autoremove removes unused packages that were installed as dependencies and are no longer needed.
5. apt clean clears the local package cache to free up space.

The script interacts with the user by asking for confirmation before performing actions such as upgrading packages, running dist-upgrade, and cleaning the system.

After each command, the script checks for errors using $?. If any command fails, an error message is displayed, and the script exits to prevent further issues.

If you’re running this on a Debian-based Linux distribution (like Ubuntu or Linux Mint), this script should work out of the box. Ensure that the user has sudo privileges for commands like sudo apt update and sudo apt dist-upgrade.

Make the script executable: chmod +x ./update.sh Run the script: sudo ./update.sh

WARNING: apt does not have a stable CLI interface. Use with caution in scripts. it is issued by the APT package manager (which is used on Debian Based Systems). It means the APT CLI interface is not guaranteed to remain stable accross version. It may change in ways that could break existing scripts, which is why the warning is issued, especially when automating tasks with scripts.

To avoid this warning and ensure the stability of your scripts, you can replace apt with apt-get or dpkg in your scripts, as they provide a more stable interface for automation and scripting.
